GSM2 click

Açıklama

• GSM2 click is the simplest way to add GSM/GPRS communication layer to your project, for fast transmission of data, voice, and SMS. It features the Quectel quad-band M95 FA GSM/GPRS module that has an integrated TCP/IP protocol stack, serial multiplexer and enhanced AT commands. The board contains a quadrupole audio/microphone jack, an SMA antenna connector, as well as a SIM card socket.

• GSM2 click is designed to run on both 3.3V and 5V power supply and communicates with the MCU over UART and the following pins on the mikroBUS™ line: INT, PWM, CS, RST and AN.

Note: the antenna is sold separately.

Quad-band frequencies
• The M95 FA supports quad-band frequencies — GSM850MHz, GSM900MHz, DCS1800MHz or PCS1900MHz. The module can search these frequency bands automatically.

GPRS data transfer
• The GPRS data uplink and downlink transfer is 85.6 kbps, which is high enough for multimedia messaging.

Power consumption
• The power consumption of the M95 FA is really low — 1.3 mA in sleep mode.

• For more information about the power consumption, see the module’s datasheet.

SMD jumper
• There is one zero-ohm SMD jumper J1 used to select whether 3.3V (default) or 5V I/O voltage level is used. Note that, regardless of the logic level, the module requires a 5V power supply in both cases.
